The two sides signed an memorandum of understanding (MoU) to this effect at the inaugural day of the 4th edition of the India Aviation Conference here.
Civil Aviation Minister Ajit Singh inaugurated the 5-day long event.
"SpiceJet greatly values the ties we have built over the years with Boeing. The Boeing Next-Generation 737 aircraft, the mainstay of the fleet ever since SpiceJet started operations, have vindicated our choice by their endurance, reliability and cost effectiveness," said S L Narayanan, Group CFO for The Sun Group.
The 737 MAX brings the most advanced engine technologies to the world's best-selling airplane, building on the strengths of Next-Generation 737, he said. It incorporates the latest-technology CFM International LEAP-1B engines to deliver the highest efficiency, reliability and passenger comfort in the single-aisle market.
"The order is a tremendous endorsement of the 737 MAX's unsurpassed fuel efficiency," said Dinesh Keskar, senior vice president of Asia Pacific and India Sales, Boeing Commercial Airplanes.
